The Great Cannon

This site is in fact the site of a "KW" cannon of the "Kaiser Wilhelm Geschutze" or "langer Max" (Max along) type which had the mission, during the First World War, to fire heavily on Belfort to create a diversion during the attacks on Verdun and the forts of Vaux and Douaumont.
Under the forest cover and around the bends, you can discover a multitude of remains that are still visible or legible. Only the "barracks" have disappeared. The buried civil engineering works are rather well preserved. During a guided tour with one of the passionate volunteers of the site, you will be able to browse the underground galleries, and discover the organization of this impressive military infrastructure. On a free visit, you will discover the surface infrastructures by following a route marked out with explanatory panels.
